Hi Ryan,
My reading is the same as your first one: that trgLang is optional except when there is one or more <target> in the document.

Subject: [xliff] Quick question on trgLang
Hi all,
As we’ve started implementing the standard, there are, of course, differing interpretations of some of the wording in the spec. Can the TC as a group please help me understand the following:
4.2.2.1 xliff
…
Constraints
· The trgLang attribute is REQUIRED if and only if the XLIFF Document contains <target> elements that are children of <segment> or <ignorable>.
Does this constraint mean:
· The trgLang attribute is REQUIRED if the XLIFF Document contains <target> elements that are children of <segment> or <ignorable>, otherwise it is optional.
Or does it mean:
· The trgLang attribute is REQUIRED only if the XLIFF Document contains <target> elements that are children of <segment> or <ignorable>, otherwise it MUST not be present.
For example, is this legal?
<xliff version=”2.0” srcLang=”en-us” trgLang=”de-de”>
…
<unit id=”1”>
<segment id=”1”>Hello World</segment>
</unit>
I think it is, but want to be sure I am reading this correctly. In a more general question, is there a reason why the verbiage “if and only if” is used throughout the spec and not just “if”?
Thanks,
Ryan
